In den heutigen Tagen ist das Lesen eines Romans mit einer gewissen Schwierigkeit verbunden. Der Mangel an Zeit erstickt uns. Wie oft beginnen wir ihn zu lesen, und kurz darauf sehen wir uns gezwungen das Buch beiseite zu legen. Beim späteren Weiterlesen haben wir schon die Namen der Personen und die Orte der Handlung vergessen. Seit dem ersten Buch, das ich im Jahr 2004 veröffentlichte, existiert dieses Problem bei mir nicht. Meine Geschichte...

This book is a product of love and respect. If that sounds rather odd I initially apologise, but let me explain why I use those words. The original manuscript was of course Freudenthal's, but his colleagues have carried the project through to its conclusion with love for the man, and his ideas, and with a respect developed over years of communal effort. Their invitation to me to write this Preface e- bles me to pay my respects to the great man...

Like preludes, prefaces are usually composed last. Putting them in the front of the book is a feeble reflection of what, in the style of mathe­ matics treatises and textbooks, I usually call thf didactical inversion: to be fit to print, the way to the result should be the inverse of the order in which it was found, in particular the key definitions, which were the finishing touch to the structure, are put at the front. For many years I have co...

Proceedings of the Colloquium sponsored by the Division of Philosophy of Sciences of the International Union of History and Philosophy of Sciences organized at Utrecht, January 1960.

The launch ofa new book series is always a challenging eventn ot only for the Editorial Board and the Publisher, but also, and more particularly, for the first author. Both the Editorial Board and the Publisher are delightedt hat the first author in this series isw ell able to meet the challenge. Professor Freudenthal needs no introduction toanyone in the Mathematics Education field and it is particularly fitting that his book should be the fi...

A title that sounds like poetry, and a subtitle that seems to contradict the title! But the subtitle is right, and originally it was just the title. A strange subtitle, isn't it? Preface to a Science of Mathematical Education. All sciences - in their prenatal stage - have known this kind of literature: only the term used was not 'Preface', but, for instance, 'Prolegomena', which * means the same though it sounds less provisional. In fact such ...
